A-803467 (944261-79-4) is a potent, selective inhibitor of the TTX-resistant voltage-gated sodium channel Nav1.8. Nav1.8 is preferentially expressed in sensory neurons, and inhibition attenuates both inflammatory and neuropathic pain in a variety of animal models. IC50's for rat and human Nav1.8 are 140 nM and 8.0 nM respectively.
